title = "Influence of ionomer equivalent weight on kinetic and transport properties in PEFC MEAs",
abstract = "The ionomer/binder type and composition can influence both ionic and mass transport in a PEFC electrode. For an electrode to have minimum resistance to O2, proton and electron transport, the ionomer composition has to be optimized for its EW and volume fraction. An optimum ionomer composition in the electrode results in higher Pt utilization and hence better MEA performance. Ion and species transport characteristics of electrode layers containing PFSA ionomers with different EWs are examined in this study by analysis of MEA polarization data at different relative humidities. Steady state polarization curves were obtained with air and oxygen. The polarization data for MEAs was analyzed to determine the relative contributions of the different sources of polarization, namely activation losses, membrane resistance losses, ohmic losses in the electrode, and mass transport losses in the GDL and electrode.",
